Folding Table Locking Member for Stable Fold-and-Store Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banquet tables are bulky, difficult to store, and require significant space due to their fixed size and heavy, complex mechanisms, making them inconvenient and costly to rent, transport, and store, especially for smaller facilities.
Innovation Solution
A foldable table design with legs that can be easily moved between extended and collapsed positions, featuring a locking mechanism that automatically locks the table top in the unfolded position when legs are extended and unlocks it for folding, allowing for compact storage and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional banquet tables are designed with fixed size and heavy mechanisms, then stability and strength are improved, but ease of operation and storage convenience deteriorate
Solution Approach 1:
The table top is divided into two foldable sections that can be collapsed together, reducing the overall footprint for storage while maintaining structural integrity during use. The legs are also segmented into collapsible sections that can be folded against the table top.
Solution Approach 2:
The table transitions from a static fixed-size structure to a dynamic collapsible structure. The table top and legs can change configuration between use position (extended) and storage position (collapsed), allowing the same object to serve different functional requirements.
2Adaptability or versatility
If conventional banquet tables have extended length, then table functionality is improved, but ease of transport and storage deteriorates
Solution Approach 1:
The table top is divided into two sections connected by a hinge, allowing it to be folded in half for transport. The legs are also segmented into multiple sections that can be collapsed, reducing the overall length and volume for storage.
Solution Approach 2:
The legs are designed to nest within or against the table top structure when collapsed, maximizing space efficiency. The collapsible leg sections are positioned to fit within the table's overall footprint when in storage configuration.
3Ease of operation
If conventional fold-in-half tables use complex mechanisms, then ease of folding is improved, but device complexity and weight increase
Solution Approach 1:
The table employs self-latching mechanisms that automatically engage when the table top and legs are in the correct position. The user simply needs to position the components, and the locking mechanism automatically secures them without requiring manual operation of complex devices.
Solution Approach 2:
Complex locking mechanisms and heavy support structures have been removed from the design. The table uses simple friction-based or spring-loaded latches that are integrated into the basic structural components rather than being separate complex mechanisms.
4Strength
If conventional banquet tables are made heavy, then strength and stability are improved, but ease of movement and transport deteriorates
Solution Approach 1:
The table uses composite construction combining wood, metal, and plastic components. This allows optimization of each material's properties to achieve maximum strength-to-weight ratio, using metal only where structural support is critical and lighter materials elsewhere.
Solution Approach 2:
The table is divided into modular sections (table top halves, leg assemblies) that can be easily separated and reconfigured. This segmentation allows for lighter individual components that can be assembled and disassembled without requiring excessive force or heavy fastening mechanisms.

AI summary
A table may include a table top and a leg assembly. The leg assembly may be moved between use and storage positions, and the movement of the leg assembly may move a cross member between a first position in which the cross member resists folding of the table top and a second position in which the cross member facilitates folding and unfolding of the table top. The table top may include first and second sections with portions that overlap and/or interlock when the table top is unfolded. When the table top is in the unfolded position, movement of the leg assembly towards the use position may move the cross member towards the overlapping and/or interlocking portions, which may move the overlapping and/or interlocking portions towards each other. When moved towards each other, the overlapping and/or interlocking portions may be securely connected.
